Answer 1

Jawaban:

13.) t=10cm

14.) panjang rusuk = 212cm volume = 74.880cm³

Penjelasan dengan langkah-langkah:

13.)L.permukaan = 2(p × ℓ + p × t + ℓ × t).

700cm² = 2(15cm×8cm+15cm×t+8cm×t)

700cm² = 2(120cm + 15t +8t)

700cm² = 240cm + 30t + 16t

700cm²-240cm = 46t

460cm=46t

460cm/46= t

10cm = t

14.) panjang seluruh rusuk= 4p + 4l + 4t

= 4×26cm + 4×12cm + 4×15cm

=104cm + 48cm + 60cm

=212cm

Volume = p×l×t

26cm×48cm×60cm

74.880cm³
